I am testing armnn+compute library on my RK3399. I want to measure the inference time using only the A53 cores. How can I exploit Compute Library functionalities to do so?
Not sure what OS you are running on top of, but there are generally two options.
From the command line you can use taskset:
* https://linux.die.net/man/1/taskset
From the software itself you can use sched_setaffinity() to do something similar programmatically.
* http://man7.org/linux/man-pages/man2/sched_setaffinity.2.html
You can set up cgroups for different core types too, if that helps.
